Anything by Scott Hahn, far and away one of the greatest Catholic authors of this generation. Dr. Hahn was a committed anti-Catholic Evangelical Protestant minister who’s intensive study of scripture led him right into the Catholic Church. He has a unique gift for making things understandable, and an incredible knowledge of scripture and knack for explaining it. Before reading his books, start with this audio presentation of his original conversion story:
Once you’ve listened to it I would start with his book that he and his wife Kimberly wrote together,
Rome Sweet Home, which gives a brief overview of some of the issues that led to their conversions. Then read
A Father Who Keeps His Promises, which takes you from Genesis through the Old Testament, into the New Testament and to the Catholic Church. That book gave me a great overview of the bible and how all the major themes are connected. Next read
The Lamb’s Supper, a beautiful explanation of the Mass and its scriptural origins. Then if you would like a great book on the role of Mary in the Catholic Church, read his book
Hail Holy Queen. For Scott, like many Protestant converts to Catholicism, Mary was a big hang up until his study of scripture showed him who Mary really is.
I cannot recommend his books enough to anyone investigating Catholicism. He has many other books as well, plus tons of videos of talks he’s given all over the country. His famous conversion story, books and talks started a wave of Protestant ministers giving up their jobs to come into the Church. Truly remarkable stories!
